  • Light Can Cool: ITMO Scientists Propose Concept of Optical Nano-Refrigerator

    A group of scientists from ITMO University, including one Master’s and one PhD student, has proposed a new method for quick cooling-down of surfaces using perovskite and light nanoparticles. In the future, this principle can be used to cool nano-lasers in optical chips, increase the life of solar panels, and create smart glass. The article was published in the journal Nanoscale.

  • Chemists 'Print' Sensors for Nano-Objects

    Young scientists from ITMO University proposed a new type of optical nano-sensors. Their operating principle is based on the interaction of light in thin films: a similar effect can be observed in soap bubbles. Such sensors can be quickly manufactured using an inkjet printer and special ink made of titanium dioxide. In the future, the sensors can be used for rapid biomedical analysis. The results are published in Nanoscale.

  • Scientists Invent Method of Catching Bacteria with ‘Photonic Hook’

    An international team of physicists has discovered a new type of curved light beams, dubbed a “photonic hook”. Photonic hooks are unique, as their radius of curvature is two times smaller than their wavelength. This is the first time that such a small curvature radius of electromagnetic waves has been recorded. A photonic hook can be used to improve the resolution of optical scanning systems, as well as to control the movement of nanoparticles, individual cells, viruses or bacteria. Results of this research were published in Optics Letters and Scientific Reports.

  • Nanoparticle Ink Lets Regular Inkjet Printers Produce Glowing Holograms

    Researchers at ITMO University have unveiled a new approach to printing luminescent structures based on nanoparticle ink. The unique optical properties of the ink were achieved by means of europium-doped zirconia. Particles of this material were proven to be useful in manufacturing glowing holographic coatings with a high degree of protection. Notably, the developed approach enables the fabrication of custom holograms by means of a simple inkjet printer. The results of the research were published in RSC Nanoscale.
